dotfiles VS nixos-config

I do what you describe in a very simple way. It's not really made for multiuser configurations as i mix home-manager config of services and packages with nixos, something i will review one day. It's a flake for macos/linux/nixos but there are certainly other more fancy repositories out there. https://github.com/sebastiant/dotfiles

My dotfiles does almost what you describe. I don't configure mulitple users but it should be pretty clear on how to do that. Hope they are of any help! https://github.com/sebastiant/dotfiles

For reference here's yet another flake example. It's very basic compared to already posted flakes https://github.com/sebastiant/dotfiles

Mine sets up a nixos host, a linux host and a macos host with nix-darwin, all with home manager: https://github.com/sebastiant/dotfiles/blob/master/flake.nix

I also took a lot of inspiration from this NixOS config that I think demonstrates a lot of things you can do with them.

The other one I've seen seems more elegant, but I've only seen once and doesn't seem to be fully explain by the author: https://github.com/MatthiasBenaets/nixos-config/blob/master/flake.nix I've tried what he's showcasing here, but it doesn't work the variables are undefined and the tips given by nix-rebuild aren't enough for me to make sense of it.

# nixos-generate-config --root /mnt # git clone https://github.com/matthiasbenaets/nixos-config /mnt/etc/nixos/ (I think this can also be avoided I forgot to check this :| ) # cp /mnt/etc/nixos/hardware-configuration.nix /mnt/etc/nixos/nixos-config/hosts//. # cd /mnt/etc/nixos/ # nixos-install --flake .#
